I remember all that you said but in this case I could not acheive a ss of1/400 there was not enough light so I would have had to boost the iso even more which I tried not to do. I was using centre focus and getting the lock on but still not sharp , so I tried manual manual focus,, shot in Live view so the mirror will be locked up ,used a tripod ,shutter release and turned the IS off and its been the first time I have seen more feathers on the bird.
Seems alot to do to get a sharper picture!!! I have shot at faster shutter speeds in the past and to no avail.
So could you tell me if my sweetspot is 325mm will it be better to crop and get a sharper picture or shoot at400 with no crop? ps I can see the dif after your editing did you just use cs4 for noise reduction?
I am putting two robin pics up again one manual and on auto focus give me your opinion please
Ps I promise if the light gets better I will use your rule everytime
